"And here is an "in-situ" image showing where I found my green rock"
Haha! If only!
I can probably borrow someone's grinder maybe tomorrow or dig though some boxes and find my dremel tool to cut off a piece. I agree that it's hard to tell with a rough stone like that. Later this month a professor of martian geology at the University of Alberta is taking me on a tour of the meteorite collection there so I will take this rock along when I go and see what he thinks as well.
"Wouldn't I be emabarassed if I was wrong, and my "wrong" wasn't?"
Nope, I would imagine that you would be too busy being ecstatic about pulling off the impossible...again!
Oh well, all is not lost. I DID find a chunk of garnet today :-) (at least I think that's what it is)

Seeing as how it's 7 AM, I think it's about time I went to bed. Goodnight all and happy hunting!
Green rock picker-upper 4 life, Graham

Hello Brother Graham and List,
http://marzmeteorite.tripod.com/mars-rocks/2mars1not.jpg
As you can tell from the above image, Brother Graham and I belong to the same fraternity - The Fraternal Order of Green Rock Picker-Uppers.
And here is an "in-situ" image showing where I found my green rock:

Actually, Graham, my story is much shorter than yours. I found my little shergo-not just last week, and only a few miles from my backyard. It was still sitting on top of my monitor when I read your message and saw your great looking image. It prompted me to share my image with you. And, as in your image, I placed a small slice of DaG 476 in front of my Mars-wannabe. For added effect, I placed a larger slice of the DaG 670 stone to the right of my m-wrong.
As a rule, I don't "hazard a guess" about a rock-type based solely on an image. Too many times I've had to change my opinion about a rock-type after examining a cut surface. So, if you show me the inside of your rock, I'll show you the inside of my rock! ;-)
It's true. I haven't cut my little rock, yet. And to be truthful, I haven't had it examined by an "expert", so I can't say with 100% certainty that my rock is a "shergo-not".
Wouldn't I be emabarassed if I was wrong, and my "wrong" wasn't?
Bob V.

Hello list
I've had this rock sitting on my kitchen table since last year when I picked it up along the side of the road while out for a walk. It is a fairly smooth green rock with black bits in it and it looks somewhat like my DAG 476 shergottite but it's a slightly lighter shade of green. I have yet to grind an end off to see what the inside looks like but there are a couple chips out of it and it looks about the same on the inside with the green part being fine grained and the black bits are individual crystals. I doubt that it is meteoritic (there is no trace of fusion crust) but I was wondering if it might be similar to a shergottite but of terrestrial origin.
Here is a pic of it: http://www.geocities.com/aerolitehunter/dag476andunidentified.jpg The small slice in the forground is my DAG 476 and the big rock is of course the rock in question.
I have been collecting rocks on and off in this area since I was a kid and I haven't seen anything like it but that doesn't mean much. I live in Alberta, Canada, where most of the rocks you find lying on the ground were brought down from various locations by the glaciers of the last ice age so it's kind of a potluck dinner of geology up here.
I won't get my hopes up, but I certainly wouldn't mind copying Bob Verish and finding out I've been sitting on a mars meteorite for a year!! :-)
Any comments are greatly appreciated Graham
